  • Patent number: 10432421
    Abstract: Provided are a communication control device and a communication system capable of detecting message transmission in the case where an invalid device transmits a message to a common communication line. A monitoring device decides a reference time point t0 for periodical message transmission by an ECU, decides multiple scheduled transmission time points t1, t2, . . . obtained by adding a period corresponding to an integer multiple of a transmission cycle T of a message to the reference time point t0, and decides that a predetermined period including each of the scheduled transmission time points is a permission period for message transmission. The monitoring device determines whether or not a detected message on a CAN bus has been transmitted during the permission period. If determined that transmission of an invalid message is not permitted, the monitoring device performs processing of causing the ECU which receives the message to discard the message.

  • Patent number: 10382328
    Abstract: Technologies are provided for distributing intra-network communications evenly across routers in a multi-tier network. Routers in a middle tier of the network receive data transmissions from a router in a lower tier of the network and determine that a destination of the data transmissions is another router in the lower tier of the network. Instead of routing the data transmissions to the destination router directly, the routers in the middle tier of the network route the data transmissions to other routers in a higher tier of the network. The routers in the higher tier of the network then route the data transmissions back to routers in the middle tier of the network, distributing the data transmissions evenly across routers in the middle tier that are connected to the destination router in the lower tier.

  • Patent number: 10375528
    Abstract: Dynamically switching between broadcast and unicast services for service continuity between wireless networks is presented herein. A system can comprise a detection component configured to determine that a mobile device is receiving a broadcast transmission of broadcast data from a broadcast enabled access point device configured to send, via a broadcast service wireless coverage area, the broadcast data to multiple devices via a point-to-multipoint communication protocol. Further, the detection component can detect a movement of the mobile device from the broadcast service wireless coverage area to a unicast service wireless coverage area. A transfer component can initiate, in response to the detection, a unicast transmission of the broadcast data from a unicast enabled access point device to the mobile device—the unicast enabled access point device configured to send, via the unicast service wireless coverage area, the broadcast data to a single device via a point-to-point communication protocol.
